Ensure that command execution is strictly blocked before logging in by enabling intensive packet blocking features within the config. Keep Software Updated
Modify your AuthMe configuration file ( config.yml ) to restrict what types of usernames can join your server.
Understanding Minecraft AuthMe Bypasses: Risks, Mechanics, and Server Security
If the backend sub-servers are not properly firewall-protected, attackers can bypass the proxy entirely. They connect directly to the backend server's numerical IP address.
If you run an AuthMe server, you are a target. Here is your 10-step hardening checklist. Minecraft Authme Bypass
Understanding Minecraft AuthMe Bypass: Vulnerabilities and Prevention
In many cases, bypasses are paired with database breaches, exposing hashed passwords. If users reuse passwords across different platforms, their external accounts become vulnerable. How Server Administrators Can Prevent Bypasses
Attempting to bypass authentication on public servers will result in permanent IP bans and coordinate bans across global gaming firewalls.
Configure an internal firewall (like iptables or UFW on Linux) to block all outside traffic to your backend server ports. Only allow connections originating from your proxy's IP address. Ensure that command execution is strictly blocked before

An AuthMe bypass refers to a vulnerability or exploit that allows players to circumvent the authentication process, effectively bypassing the security measures put in place by the AuthMe plugin. This can be achieved through various means, including exploiting software bugs, using third-party software, or manipulating game data. When a player successfully bypasses AuthMe, they can gain access to a server without providing valid login credentials, potentially leading to account theft, server damage, or other malicious activities.
Install the BungeeGuard plugin on both your proxy and your backend backend servers. It utilizes a secure token system to ensure backend servers only accept connections originating from your specific proxy.

Malicious actors may install backdoors, delete entire worlds, or threaten to keep the server offline unless a ransom is paid. How to Protect Your Server Against AuthMe Bypasses
: Ensure sub-servers are only accessible through the BungeeCord/Velocity proxy. Enable ProtocolLib ProtocolLib
AuthMe is a popular authentication plugin used on Minecraft servers to manage player accounts and ensure secure login processes. Developed to combat the issue of account theft and unauthorized access, AuthMe requires players to authenticate their accounts before joining a server. This plugin has been widely adopted by server administrators due to its effectiveness in preventing account hijacking and promoting a secure gaming environment.
For players, the best approach is to protect their own accounts. For administrators, the focus should always be on robust configuration and keeping server software up to date.
The history of AuthMe is marked by repeated patterns of "bypass" events. Analyzing these patterns reveals that the majority of successful bypasses come from network misconfigurations rather than the plugin's core login algorithm.
Warning: The following is for server administrators to understand attack flows. Do not use this maliciously.
